High transmission and practically no diffusion.
Can also be used for a combination of several dedolights in spot or medium focus position (all with equal focus and intensity settings – DMX), placed in parallel direction to achieve a uniform band of light.
Similar effects have always been possible on focusing studio lights or lights with a defined beam angle by adding a gel filter called "brushed silk".
This is still valid, but will always produce a noticeable amount of diffusion at the same time as spreading the light beam in one direction.
With the unequalled dedolight and it‘s clean beam concept, these directional beam spreaders DWAFX allow the spreading of the light without causing diffusion.
